问题描述
我在Windows XP上使用Visual Studio 2008,问题是我试图打开一个文件对话框以选择一个文件,在WinXP上这可以正常工作,但在Windows7上却没有显示文件对话框.这是我的代码
I am using Visual Studio 2008 on Windows XP, the problem is that I am trying to open a file dialog box to select a file, and on WinXP this works fine but on Windows7 the file dialog does not show. This is my code
OpenFileDialog FD = new OpenFileDialog();
FD.Title = "Images";
FD.Filter = "Png Images| *.png";
FD.ShowDialog();
if (FD.FileName.ToString() != "")
{
pngImage.ImageLocation = FD.SafeFileName.ToString();
img = new Bitmap(FD.SafeFileName.ToString());
}//end if
推荐答案
该代码在哪里调用?是在Form_Load或Form_Shown事件中的某个位置-在某些情况下,不会显示在那里引发的异常.
您可以逐步调试程序直到ShowDialog()
调用吗?
Where is that code called? Is it somewhere in a Form_Load or Form_Shown event - under some circumstances, exceptions thrown there are not shown.
Can you debug the program step by step downto theShowDialog()
call?
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.InitialDirectory = "c:\\";
openFileDialog1.Filter = "All files (*.*)|*.*";
openFileDialog1.FilterIndex = 1;
openFileDialog1.RestoreDirectory = true;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
//openFileDialog1.FileName
}
这个在win7中对我有用
This one works for me in win7
FD.FileOk += new CancelEventHandler(openFileDialog1_FileOk);
private void openFileDialog1_FileOk(object sender,
System.ComponentModel.CancelEventArgs e)
{
if (FD.FileName.ToString() != "")
{
pngImage.ImageLocation = FD.SafeFileName.ToString();
img = new Bitmap(FD.SafeFileName.ToString());
}//end if
}
